Other Situations Involving Group Matrices

Kenneth W. Johnson

Research output: Chapter in Book/Report/Conference proceedingChapter


This chapter sketches various situations in which the tools described in this book have appeared. They are: 1.The characterization of those class functions on a group which are group characters.2.The use of group matrices in the theory of group rings.3.The application of group matrices to the theory of cogrowth of groups.4.Work of Poincaré on differential equations.5.The connection between factors of the group determinant and Chern classes.6.The appearance of the group matrix as a Gram matrix for tight frames with a symmetry group, which have appeared in the theory of wavelets.7.The theory of 3-manifolds.8.Control theory and electrical engineering.9.The algebra defined by considering the k-classes under multiplication.
